I’ve been taking the Hormone Harmony…
I’ve been taking the Hormone Harmony for over a month now and could see some slight changes. Will continue to use and hope I get greater results after taking them longer. I’m very happy with them so far.

Hormone Harmony really helped
I took Hormone Harmony for a month and my emotions got more balanced. I started to get my lust back for my husband. Suddenly I could feel things again that I hadn’t felt for a couple of years. But because I thought it was quite expensive I tried something else, similar, for a while but I didn’t get the same results. Decided to start with Hormone Harmony again an stick with it. And I am back on track again. I still think it is a bit expensive but for now I will make that a priority.

I’m not going to lie I was…
I’m not going to lie I was sceptical…..but I have been taking hormone harmony for well over 1 year now and it has made such a huge difference for me. It works and does what it says or does……I even stopped taking it for a few months to see if it was actually doing anything…..and boy was that a mistake. I’m now on a subscription so I don’t run out. I’m way more harmonious taking hormone harmony. Love it

A positive start under difficult circumstances
The information on the products is excellent, and the customer service is very good.
I would have loved to be one of the customers who saw an immediate change, but, unfortunately for almost the first two weeks, I had a really heavy cold and then went on an all inclusive holiday!
However, having said that, I think I have seen changes - sleep patterns are improving and I think I feel less fatigued, but difficult to assess with the cold. I am definitely happy to keep going and hopefully will have the chance to update this re.view

Quality products
I have been faithfully subscribed to Happy mammoth hormone harmony for over 2 years for perimenopausal support. The quality of these supplements are reflected in the elimination of hot flashes from my nightly routine. That was my sole reason for purchase of this product. Huge thanks from a satisfied customer!

So far so good
I cannot say much yet about the effect, as I am only halfway through the first bottle but what I can say is that the capsules are super soft on the stomach. I feel bothing even on an empty stomach which says a lot as I am very sensitive. Energy levels are good and I have no hunger afer 5pm. I am using the weight loss support product.

Dont buy ! Scam!
Still lots of bloating, sweats and does not do anything as what you promote your product does ! Scam! And will be reported. Expensive is one thing .. but to scam and earn on women who is desperate to be relieved of symptoms .. i guess you guys sleep well at night as we are beeing robed of hope, trust and just in general actually believe in that crap we are swallowing! 🥳🤮👹👺
